On Olivia's one month birthday I tried to get a video of her rolling over, since she'd done so earlier in the day. It didn't happen, but here is the video anyway. True to form, Dee had to come running the minute she realized Olivia was on the floor.
Once Dee settled down, I tried again. Still no luck, but Olivia does start licking the mat, which I thought was funny. I guess she was getting hungry.
